NSB Di 1 was a class of diesel-hydraulic locomotives built by Krupp for the Norwegian State Railways (NSB). The locomotive had two MAN diesel engines, giving a combined power output of 1,472 kilowatts (1,974 hp) and allowing the 82.7 tonnes (81.4 long tons; 91.2 short tons) vehicle to reach a maximum speed of 100 km/h (62 mph). It had a 1'BB'1 wheel arrangement and a driver's cab at only one end.
Two units were ordered in 1937, but only one locomotive was delivered, in 1942. Numbered 601, it was the first diesel locomotive used by NSB. It first served on the Bergen Line, although the locomotive was plagued with technical faults causing it to be out of service for shorter and longer periods. The locomotive was moved to the Dovre Line from 1952 and finally to the Gjøvik Line and Kongsvinger Line from 1957. The locomotive was retired and scrapped in 1959.
